---------------------------------
Resolution: Fixed
> file descriptor leak in axis2_http_transport_utils_get_services_static_wsdl
> ---------------------------------------------------------------------------
>
> Key: AXIS2C-1448
> URL: https://issues.apache.org/jira/browse/AXIS2C-1448
> Project: Axis2-C
> Issue Type: Bug
> Components: core/transport
> Affects Versions: 1.5.0, 1.6.0
> Environment: All
> Reporter: Matt Mason
> Priority: Blocker
> Fix For: 1.7.0
>
>
> This problem affects at least 1.5.0 and 1.6.0. I haven't checked any earlier
> versions.
> When viewing the wsdl via services/ServiceName?wsdl
> the wsdl is opened with a call to fopen and the result assigned to a local
> FILE* variable. However there is no corresponding call to fclose.
> We have a monitoring script that periodically requests the wsdl to check that
> the service is available.
> The process (currently) has a limit of 1024 open file handles, eventually
> this leak causes that number to be exceeded.
> The client library we use to connect to the service also requests the wsdl
> file when connecting to the service.
> With reference to the code in the 1.6.0 release, here is the 1 liner to plug
> the leak.
> Regards,
